Why are nodes being duplicated while testing in sproxy?

I have created a soap to proxy synchronous scenario and while testing in sproxy, the nodes are being duplicated. I have given the occurrence of the node as 0:unbounded.

The node is like:

<Output Table 1>

<Item1>String<Item1>

<Item2>String<Item2>

</Output table1>

<Output Table 1>

<Item1>String<Item1>

<Item2>String<Item2>

</Output table1>

<Output Table 1>

<Item1>String<Item1>

<Item2>String<Item2>

</Output table1>

But this should not get repeated,if there is just one entry(Getting repeated), if multiple entries are found then accordingly the output table node should come I found that in the code sproxy generates, there is a DO loop appending 3 times to out parameter. I doubt if it is because of this. Please advise.
